1. Power adapter: Input 100-240V AC / Output 12V 1A DC
2. Purpose: test spark plug performance and ignition strength
3. Application range: 12V gasoline engine automotive spark plugs
4. The dual-hole automotive spark plug tester has two test holes, which can test two spark plugs at the same time. If you suspect that any spark plug is not working properly, you can do a comparative test to make an accurate judgment
5. Test principle: In the automotive ignition system, the high-voltage ignition coil generates a high voltage (more than 10,000 volts), and the spark plug leads it to form a high-voltage ignition coil into the cylinder engine. The spark between the spark plug electrodes ignites the mixture. The detector can distinguish good spark plugs from bad spark plugs according to the intensity of the spark
6. Turn the key switch clockwise to turn on the tester, and the indicator light is green
7. Close the protective cover, insert the adapter into the side socket, and connect the tester to the power supply to turn it on
8. Turn the switch clockwise to adjust the operating frequency between 1000rpm and 6000rpm/min. The higher the frequency setting, the stronger the spark.
9. Dimensions: 145x85x60mm
10. Weight: 354g

Instructions for use of the automotive spark plug tester:
1. Turn off the power before placing the spark plug
2. The spark plug tester is a high-voltage detector. Do not touch the spark plug with your hands during operation to avoid danger
